 Milestone:
 
-    On May 6 of 2023, a test was completed, and the entire scene was drawn with only one DrawCall. Although it still has a lot of unfinished work, it is still a very important milestone.
+    2. Texture2DArray was integrated into material instances. 
+    Multiple render instances of the same model use different material instances and textures but are still merged into one render. 
+    Although the changes this time are small, they are more significant.

 里程碑:
 
-    2023年5月6日，完成了一个测试，只用了一次DrawCall就绘制出了整个场景。虽然它还有很多未完成的工作，但它依然是一个非常重要的里程碑。

+    2. Texture2DArray集成在材质实例中。同一个模型的多个渲染实例使用不同的材质实例以及不同的纹理，
+    但它们依然被合并成一次渲染。这次的改变虽小，但意义更为重大。
